MK0 Bottom Brackets take performance to another level with aggressive machining, custom ceramic bearings, and intricately designed race sealing built to Wolf Tooth's exacting specifications. This design saves you watts while proving durable enough for the most intense off-road racing, inclement conditions, and are fully serviceable.
MK0 components are proudly machined at Wolf Tooth HQ in Minnesota, USA.
No Compromise
Durability and ceramic bearings haven't always gone hand-in-hand. Where many ceramic bottom brackets are known for spinning with low friction, they're not known for making it through even a few months of riding in harsh conditions. Wolf Tooth's MK0 ceramic bearings feature custom race sealing for flawless performance against the elements and endless speed.
Built To Endure
Custom bushings separate the bearing inner race and crank spindle to eliminate metal-on-metal contact, the leading cause of bottom bracket creaks. This bushing also helps enhance bearing longevity with an interface to the bearing gutter seal for maximum weatherproofing. No metal-on-metal contact, no creaks.
